Gevor won his first professional titles when, on December 3, 2005, he stopped Mexican Gustavo Magallanes in the eighth round and won the vacant
IBF and
WBO Inter-Continental middleweight titles. He defended both titles against
Sergey Khomitsky before vacating them soon after. Gevor fought against compatriot
Arthur Abraham for the
IBF Middleweight title on August 18, 2007. Gevor was defeated by an 11th-round knockout from a powerful left hook. On November 28, 2008, Gevor beat Finn
Amin Asikainen in his hometown of
Helsinki by 7th-round knockout and won the European championship belt. Gevor lost a controversial bout to
WBA Middleweight Champion
Felix Sturm by unanimous decision on July 11, 2009. On April 9, 2011, Gevor fought
WBO Super Middleweight Champion
Robert Stieglitz in a very competitive brawl. Gevor received a cut over his left eye in round three. The fight got more dirty in round ten when, after referee Manfred Küchler deducted a point from Gevor, both fighters wrestled each other onto the canvas. Stieglitz emerged with a cut over his right eye and Gevor was disqualified by the referee. Angry, Gevor attacked Küchler and was removed by security. Gevor fought Baker Barakat in a six-round bout on December 10, 2011. The whole fight was fairly even. As soon as Barakat was announced the winner by decision, Gevor turned to the referee and punched him in the face. Barakat and people from both corners tried to hold Gevor back. Later in the dressing rooms, the fighting continued and police had to be called in to break it up. ==Personal life==
